You may not use this at your job, or you may, but you'll use it in everyday life outside of your job. Unlike the social sciences, where everyone has a thoery about everything that disputes everyone else's theory and you have to memorize 30 different scientists about theories that are easy to understand, math is concrete and works the same everytime. My dad loved this and feels right at hoem. His english skiss are another issue. It will take you a while to get it but when you do it will all fall into place. My wife's a social worker who uses very little if anything from her psych or MSW classes. But she wishes she understood math better earlier so she knew how interest really worked and how much money we are now throwing away.
